Just to check are U a Hainan cause most folks there speak Hainan (young gen can speak Chinese).
Hi if are U going to Hainan, the shops there will not be closed but as a reminder most of the shops are selling winter wear now and not much stuff for summer ( I went last year Nov). To be frank with you Hainan Island is a tropical island and most north people like to go there for summer vacation. Places to visit will be Bo Ao, Qionghai and Sanya (is hot even in winter cause is at the end of Hainan Island). If U stay there do look out for good hotels. U can check hotels at
